HENRY JAESOHKE, OF SCIY LOUIS, MISSOURI.

COMBINED MUSICAL INSTRUMENT AND STOOL.

SPECIFICATION forming part of Letters Patent No. 270,075, dated January.2, 1888.

Application filed August 16,1882. (No model.)

To all whom it may concern Be it known that I, HENRY JAESCHKE, of thecity of St. Louis, in the State of Missouri, have invented a certain newand useful Improved Combined Musical Instrument and Stool, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification, and inWhich Figure 1 is one-half in rear elevation and one-half in verticalsection on line 1 1, Fig. 2. Fig. 2 is a transverse section taken online 22, Fig. 1, with the key-board open. Fig. 3 isa detail view withthe key-board in its closed position and Fig. 4 is a similar view withthe keyboard in its open position, which brings the back ends of thekeys into engagement Fig. 5 is a top view with half of the top of thecase removed and the key-board open. Fig. 6 is an enlarged detailvertical section taken on line 6 6, Fig. 1.

My invention relates to a musical instrument to be operated by the feet,on which the bassnotes of a common organ can he played, and,

thus it can be used to accompany any kind of hen in use the operatorsits on the case of the'instrument, and it can thus be used as a stoolor bench when the same operator is playing it and a piano or organ orother musical instrument. When not in use the key-board can be closed upand secured in place by suitable springcatches, giving to the instrumentthe appearance of a rectangular box, which can be used as a bench in anypart of the room, thus becoming an article of furniture.

My invention consists in the novel arrangement and construction of partshereinafter fully described and claimed.

A represents a rectangular box or case, the back being provided withpanelsto allow the escape of the sounds, the front B of which forms thekey-board of the instrument, which is pivoted at'O to the front lowercorners of the ends of the case, so that it can be opened out into theposition shown in Figs. 2, 4, and 5 and rest upon the floor.

To the key-board, near its hinged end, is secured a strip, D, andvertically above this, secured to the sides ot'the board, is asecondstrip, 1*]. The inner ends of the keys B fit between these strips, andare connected therewith by pins F, which pass through longitudinal slotsin the keys. Suitable felt cushions are placed between the keys and thestrips, as shown. The inner ends of the keys have projections G, withupturned ends or teats H, which bear'respectivelyagainst the under sidesof the valveoperating levers I, which are pivoted by their rear ends atJ to a strip, J, which is made fast to the ends of the case. It willthus be seen that when the outer ends of the keys are depressedtheirinner ends will raise the valves through means of the levers. The outerends of the keys are supported by springs 13?. (See Fig. 2.) The blackkeys, which would correspond with the black keys ofan organ or piano,arelower than the white ones, buthave upward projecting ends, whichextend above the white keys, (see Fig. 2,) so that either can beoperated without operating the others.

The instrument operates by air being sucked through the reeds by meansof bellows, which are preferably made in pairs K, as shown, eachconstructed as follows:

L is a partition-board extending all the way across the case from end toend, and inclined vertically, as shown in Fig. 2. It is secured to thecase, and its lower end comes against a rectangular housing, M, in whichthe reeds are located.

M is a strip connecting the top of the lions ing and the inclinedpartition-board. (Ste Fig. 6.)

In front of the partition-board, and connected therewith by suitableflexible material, (see Fig. 2,) is a board, N, and toits rear, andsimilarly connected therewith, is another board, N, to which theoperating-leverO is connected by straps, O, which pass over pulleys orrollers 0 secured to the top or back of the case. There are two of theseboards N and two N, which form the double bellows. The lever isfulcrumed at 0 to the case, at a point about midway between the strapsO, and thus when it is operated it will act alternately on the bellows KK. When the boards N are pulled out by the lever they are forced back byV- shaped springs P, located between them and the back of the case. (SeeFig. 2.)

Instead of hinging the boards N to the case by their lower ends, Isecurearms N to them, which are pivoted at their lower ends to the extremelower part of the case, and I thus increase the radius of the circleupon which they move.

WVhen the bellows are worked and the valves raised, as hereinafterdescribed, by operating the keys air is drawn through the reeds, asshown by the arrows, (see Fig. 6,) passing through an opening, L, in thepartition-board L, and then back through another opening, L in theboard. (See Fig. 2.) When theboards N are forced back by the springs theair in the bellows escapes through flap-valves N on the back of theboards.

Q are set-screws on the inner ends of the levers I, which have cushionsQ on their upner ends, which, when the keys are depressed, come againststems R, depending from the outer ends of valves R, which cover openingsin the top of the housing M. The stems are guided by projections orstrips It on the back of the housing,through which they pass. The frontends of the valves are guided by pins R extending up through them fromthe top of the housing. The valves are held down, except when raised bythe keys, by springs R secured to the partition-board. (See Fig. 6.) Thesprings are removable, so that by detaching them the valves can beraised vertically and removed.

S are reeds secured to frames S in the ordinary manner. The frames aresecured to the back wall of the housing in frontof openings T in anysuitable manner. (See Figs. 6 and 7.)

To tune the reeds I pass a set-screw, 8, down through the overhangingprojections S of the upper ends of the frames S. On the lower ends ofthe set-screws are nuts 8, which bear against the reeds, as shown, andby turning the screws the nuts will be moved up or down and their pointsof bearing on the reeds lengthened or shortened, thus limiting orincreasing their amount of vibration.

The boards N are held away from the parti' tion-board, when in theirnormal positions, by

V-shaped springs N (see Fig. 2,) and to prevent this board destroying orbreaking some of the parts by too violent an operation of the lever O,or when the lever is worked and the keys not operated, so that aircannot enter through the valves, I make openings through the boards andcover them with flap-valves N on the outside, and put pins N in thepartition-board, (see Fig. 2,) so that when the boards Napproach thepartition-board the pins will strike the valves and open them, allowingtheairto rush in and supply the vacuum.

Ifdesired, the bellows can be worked by suitable springs, which would bewound up similar to a cloclcspring, instead of the lever.

If desired, the operating-lever may be connected by suitable means to asecond lever, which would be within reach of the player, so that he canwork the bellows. Instead of reeds, strings may be used, similar to anupright piano.

I claim- 1. A combined musical instrument and stool, consisting ofmusic-stool having a side hinged to turn down, and foot-keys and leversfor playing the instrument, as set forth.

2. Acombined musicalinstrumentand stool, consisting of a case, A, hingedside B, footkeys B, pivoted to said side,having extension G, providedwith upturned ends II, levers l, hammers Q, vertical rods 1%, horizontalvalves R, depending reed-box M, reeds S, bellows K, andbellows-operating lever O, as set forth.

3. In a musical instrument, the boards N of the bellows, having arms Non their lower ends, by which they are connected to the lower part ofthe case to increase the radius of their circles, as set forth.
